164 AMERICAN COLEOPTERA 



C. temporalis sp. nov. — Moderately elongate, feebly convex, rufotesta- 

 ceons; pubescence pale, recumbent. Head finely but distinctly, rather sparsely 

 punctate; eyes much smaller than usual, tempora nearly as long as the eye. 

 Antennae rather short, not reaching the hind angles of the pro thorax, joints 7-10 

 as wide as long. Prothorax transverse, widest a little before the middle, sides 

 moderately rounded anteriorly, a little sinuate before the hind angles, which are 

 only slightly obtuse; base and apes subequal, margin finely serrulate; surface 

 moderately punctate, the punctures distant by fully their own diameters ; basal 

 fovea somewhat transverse, distinct but not deep. Elytra two-thirds wider than 

 tin- prothorax, stria- faintly impressed toward the base; punctures moderate, 

 those of the interspaces finer, all finer toward the apex. Beneath sparsely, finely 

 punctate throughout, the abdomen indistinctly so. Metasternum distinctly 

 longer between the coxae than the first ventral at sides; middle coxae separated 

 by barely two-fifths the eoxal width. Eegs rather slender. (PI. V, figs. 55 

 and 55«). 



Male.— Unknown. 



Female. — Tibije straight; fifth ventral slightly longer than the fourth and un- 

 impressed. 



Length 1.4 mm. 



II'ib.—Texns (El Paso). 



A single female taken by myself by sifting along the Rio Grande 

 River. The small size, small eyes, and very long tempora are suffi- 

 cient to separate it instantly from any other species known to me. 



C brevicornis sp. nov. — Elongate, depressed, rufotestaceous; pubescence 

 of moderate length, recumbent. Head sparsely but distinctly punctate; eyes 

 large, prominent, tempora about one-fifth as long as the eyes. Antennae rather 

 short, sixth joint subglobular, 7 and 8 a little transverse, 9 and 10 strongly trans- 

 verse. Prothorax transverse, subeordate, moderately rounded in front, base a 

 little narrower than the apex ; surface moderately closely punctate, the punctures 

 separated by about their own diameters at the middle, but rather closer at the 

 sides; basal fovea moderately deep and a little transverse ; margin crenato-den- 

 ticulate. Elytra about one-third wider than the prothorax, oblong, parallel, 

 sides feebly arcuate, apex obtusely rounded; punctures of stria?, and interspaces 

 moderate. Beneath sparsely, finely punctate, indistinctly so posteriorly. Meta- 

 sternum longer than the first ventral ; middle coxae separated by more than half 

 tin eoxal width. Eegs rather slender. ( PI. Y, tigs. 56 and 56a). 



Male. — All the tibise bent and mucronate within at tip, the posterior pair less 

 distinctly so; fifth ventral usually not longer than the fourth and unimpressed, 

 tin- sixth normally visible. 



Female. Tibiae straight; fifth ventral but slightly longer than the fourth and 

 unimpressed; sixth visible. 



Length 1.6 1.75 mm. 



Huh.— Massachusetts (Tyngsboro'— Blanchard) ; Michigan (Mar- 

 quette) ; Florida (Tallahassee— Hubbard and Schwarz). 



A.s indicated by the localities given this is a somewhat widely dis- 

 tributed species, hut it is probable that it is confused with elongata 



in collections. The differences are numerous and are principally as
